Anyone on this board who can share any information on reloading .444marlin with VV N32C Tin Star. I don't know if there are any cowboyloads for this caliber?

It would be nice to show loads for the SAAMI spec 257 Roberts +P. It is based off a max average pressure of 58K psi as compared to 54K for the standard 257 Bob.
Cannot seem to find 6.5 Carcano load data. Am I just looking in the wrong place, or is it because the mixed diameter used in the Carcano(.264 and .268) ?
I have a Gunwerks Nexis Rifle in 7mm PRC (24 inch barrel with 1:8 twist). I currently use Peterson Brass with Retumbo powder. I would like to load 195g Berger EOL bullets and would greatly appreciate experience with this load- COAL, grains of powder, velocity etc.
I am new to reloading so happy to listen and gain experience.
Many Thanks
